The constant level is equal to the level of the displayed video signal during the preceding continuous X-ray analysis. In operation when switch S3 is actuated the X-ray generator 1 and X-ray source 2 are switched from the condition in which they produce a low level X-ray signal for continuous X-raying (monitor 8 being viewed) to a condition in which they produce a short pulse of high intensity X-radiation for taking a photograph. Simultaneously the gain of amplifier 12 is controlled as above i.e. reduced and then gradually increased, and the control signal to an AGC circuit 13 is locked to the value it had at the end of the preceding period of continuous X-raying. In addition a circuit for controlling shutter 11 is actuated so that the shutter is opened before the occurrence of the X-ray pulse and is closed after a plurality of television image scan cycles. The amplifier 12 may comprise an electron multiplier associated with an image orthicon camera tube in which the voltage on one of the dynodes is switched (Fig. 3, not shown).

Abstract: 1,150,463. Gas lasers. WESTERN ELECTRIC CO., Inc. 30 Sept., 1966 [14 Oct., 1965] No. 43725/66. Heading H1C. A gas laser includes as the active medium a mixture of nitrogen, helium and either carbon dioxide or nitrous oxide. The mixed gases are continuously pumped into a tube 20, at least two inches in diameter. A D.C. discharge is set up between oxide coated platinum cathodes 14, containing barium and strontium carbonates, and anode 15. A coolant such as water or methanol is passed through outer tube 21 to increase the difference between the rotational and vibrational temperatures of the carbon dioxide. A resonator, consisting of mirrors 33, 34, the former having an aperture through which the output is obtained, may be provided or, if a straight-through amplifier is required, may be omitted. Alternatively, additional mirrors may be provided to form a ring laser, or the two mirrors may be adjusted to define non-overlapping paths for a multi-pass amplifier. The mirrors may be outside the tube 20 if Brewster windows are provided. Tube 20 may be of glass, plastic or quartz and is about three meters long. The laser output may be detected by a calibrated thermopile or may be passed through an electro-optic modulator. The gas pressures should lie in the ranges, CO 2 :N 2 :He, 0À2 to 0À4: 1À0 to 1À5: 3À0 to 10À0 Torr. Pumping may be provided by a radio frequency discharge instead of a D.C. discharge. Theory.-The helium atoms are ionized by the D.C. discharge and decay quickly to the 19À8 ev metastable state. The metastable helium atoms are each capable of dissociating two nitrogen molecules to give 9À9 ev nitrogen atoms. These atoms decay through higher vibrational levels and then through four more equally spaced vibrational energy levels to the ground state. The energy produced in each of these latter transitions is equal to that required to excite the 00‹1 vibrational level of the carbon dioxide molecules. Stimulated emission then occurs between this level and the 10‹0 level. Nitrous oxide has energy levels similarly spaced to these energy levels of carbon dioxide.

Title: Process for the manufacture of fibre-reinforced moulded products
IPC: B29C43/00
Filed: 1961-12-08
Abstract: Fibre reinforced resin products are produced by distributing a thermosetting resin powder in or on a felt and then placing the felt in a moulding press heated to the curing temperature of the resin, the press being repeatedly opened and closed to cause the fusion of the resin and its distribution throughout the felt and then to cure it.  Corrugated plates, for example, are formed by first depositing, using a vibratory sprinkler, a uniform layer of 750g/m2 of a powdered phenol formaldehyde resin on a strip of needled jute felt.  A second identical felt is placed on top and the two are passed, to become seni-rigid, through two calender rolls heated to 120 DEG C.  The strip is cut into plates and two of them, separated by a metal sheet or non adhesive film, are put in a press capable of exerting a pressure of 1800 tons and provided with two corrugated mould members heated to 165 DEG C.  After three cycles each of a 15 second closure followed by a 5 second opening there is a fourth closure of 45 seconds.  The method may be modified for other objects, i.e. motor housings, by passing the felt on a conveyer under a resin distributer, and the calendering process may be replaced by using a press or may be omitted.  The pressure in the fibre of some water, say 3-6% per weight of the fibre as a minimum is advisable.  The felt may have been impregnated with the resin before it was needled.

Abstract: 1488887 Welding by pressure; broaching CLARKE CHAPMAN Ltd 21 Oct 1975 [15 Oct 1974] 44708/74 Headings B3R and B3L In a method of friction welding wherein two workpieces are rubbed and forced together so forming flash 100 at the weld junction, one of the workpieces 10 being gripped in a rotatable assembly of a friction welding machine, said assembly includes a flash removal device, e.g. an annular shearing tool 32, which is advanced axially to remove the flash 100. As shown in operation, two workpieces 10, 12 are gripped in jaws 24 of a chuck 22 of the rotatable assembly and a clamp (not shown) respectively. The workpiece 10 is rotated and advanced toward the workpiece 12 by the action of a spindle 16. An hydraulic ram (not shown) governing the advance of the spindle 16 is energized to provide first pressure level between the workpieces then a second, higher, pressure level followed, after stopping of the workpiece 10, by a forging pressure, higher than the preceding pressure level, which forging pressure produces the weld and the flash 100. The annular shearing tool 32, which is rotatable with the spindle 16 and the workpiece 10 during welding, is then axially advanced by a non-rotatable hydraulically activated piston 80, so removing the flash. The annular shearing tool 32 may include three helical working faces (Fig. 2, not shown) or a continuous annular working face (not shown). In a modification (Figs. 3, 4, not shown), the annular shearing tool comprises resilient portions which when contacted by the jaws of the chuck grip the workpiece 10, the chuck releasing its grip during the shearing operation. The invention is also applicable to a "fixed head" type apparatus wherein the second workpiece is advanced by a ram, and to where the axis of rotation is upright or inclined to the horizontal.
